BAFFAELE CARBONARI, OF CHICAGO, ILLINOIS.

ACCORDION.

Application filed June 10, 1916.

To all whom it may concern:

Be it known that I, RAFFAELE CARBONARI, a citizenof the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Accordions, of which the following is a specification.

This invention relates to accordions; and has for its object to improve a device of this character in such a manner that its keyboard will be like that of a piano and thus enable one accustomed to playing a piano to play the accordion without previous training.

In carrying out this object I employ a double keyboard, one at either side of the accordion, each made up of piano keys so arranged that the bass notes will be accessible to the left hand and the treble notes adjacent to the right hand of the player, with their scales running in opposite directions.

My invention is exemplified in the following description and illustrated in the accompanying drawing, in which- The figure shows a plan view of an accordion embodying my invention.

An accordion is shown in the drawing, which may be of any preferred construction, having a bellows 10 and playing parts 11 at either side of the bellows. Included in each of the playing parts, at opposite sides of the bellows, is a. keyboard 12 made up of a series of keys 13 like those of a piano. The left hand keyboard represents the bass notes on the accordion, with the lowest tone starting at the outer end, while the right hand key board represents the treble notes, with the highest tone ending at the outer end.

When the accordionis held in the usual pla ing position by an operator, the rising scale on the bass or lower clef will be toward the operator, while on the soprano or upper clef the rising scale will be away from the operator, which is substantially the arrangement of a piano keyboard.

A strap 14 is provided for the left hand side of the accordion and encompasses the front of the keyboard, so that the operator may insert his hand between for operating the bellows, which arrangement permits of the free movement of the hand along the keyboard for actuating the keys. The keyboard on which the strap is arranged is referably provided with a less number of keys than the opposite keyboard, as the free Specification of Letters Iatent.

hand of the operator can cover a wider range of keys.

Obviously, such an arrangement as shown and described herewith requires no appreciable increase in the size of the accordion and may be carried out in the same manner to accommodate any desired number of playing notes.

It has been proposed heretofore to substitute piano keys for the usual buttons of an accordion at the treble notes only, but, obviously, this is not the equivalent of the present arrangement inasmuch as a piano player without special training cannot play such prior devices on account of the presence of the peculiarly arranged buttons remaining at the bass notes.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. In an accordion, a playing keyboard at both sides thereof, said keyboards each comprising a series of piano keys, those controlling the bass notes bein arranged at one side and those controlllng the treble notes at the other side of the accordion.

2. In an accordion, a playing keyboard at both sides thereof, said keyboards each comprising a series of piano keys, those controlling the bass notes bein arranged at one side and those .controlhng the treble notes at the other side of the accordion, and having their scales running in opposite directions.

3. In an accordion, a playing keyboard at both sides thereof, said keyboards each comprising a series of piano keys, those controlling the bass notes being arranged at one side and those controlling the treble notes at the other side of the accordion, and having their scales running in opposite directions, and a strap encompassing one of said keyboards in a manner to permit the insertion of the operators hand between for moving the bellows.

4. In an accordion, a playing keyboard at both sides thereof, said keyboards each comprising a series of keys like those of a piano, those controlling the bass notes being arranged at one side and those controlling the treble notes at the other side of the accordion and having their scales running in opposite directions, and a strap encompassing the front of the bass keyboard in such a manner as to permit the operator to insert his hand the treble notes being arranged at the oppobetween for moving the bellows, said bass site side with the rislng scale running away keyboard comprising a less number ofkeys from the operator. than the treble keyboard. In testimony whereof I have hereunto set 5 5. In an accordion, a playing keyboard at my hand in the presence of two subscribing 15 both sides thereof, said keyboards each comwitnesses.
